IMPROVEMENT IN CAR-COUPLINGS.

Specification forming part of Letters Patent No. 1 68,399, dated October5, 1875; application filed August 28, 1875. v

To all whom it may concern:

Be it known that I, JOHN H. J oHNsON, of Brooklyn, in the county ofJackson and State of Michigan, have invented a new and ImprovedCar-Coupling, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a front elevation of myimproved carcoupling; Fig. 2, a side view, and Fig. 3 a bottom View, ofthe same.

Similar letters of reference indicate correspondin g parts.

The invention will first be described in connection with drawing, andthen pointed out in the claim.

In the drawing, A represents a draw-head with tapering month, applied bycushioning spring and supporting devices to the bottom of the car-frame.A coupling-link, B, passes in longitudinal direction through thedrawhead, and projects with its arrow-shaped head to the outside of thesame. The link B is fulcrumed to a vertical adjustable bolt, a, andconnected at the rear end to a lever, rod, or hook, I), that is attachedto a vertical leverhandle, 0. The lever 0 is fulcrumed and guided insuitable manner at the oar, to be operated from the top, side, orplatform of the same, for swinging the front end of the linkB to eitherside, for the purpose of uncoupling the same from the similarly-shalmdand interlocking link of the connecting draw-head. The link rests on aninside shoulder of the fulcrum-bolt a, and may be raised or loweredthereon for throwing the arrow-head into lower or higher position. Alateral rod, d, passes through the mouth of the draw-head, and throughthe link back of the arrow-head, for the purpose of steadying the sameand guiding it when carried to either side by the uncoupling-levermechanism 0. Spiral springs d of rod (1 act on each side of the link tocarry it back to a central position in the drawhead after uncoupling,ready for coupling.

The arrow-head of the link B is recessed and perforated to couple withcars having the common pin-and-link coupling. Aforked lever, D, isconnected to the rear part of the drawhead A by a vertical bolt, 0, andfulcrumed to a pivot-pin, f, of the car. The pivot-pin f is strengthenedby a connecting link, f, that extends to the pivot of a weighted pawl,g,

arranged above the fulcrum f of the lever. The pawl 9 looks into stopsor notches g of the lever, to retain the same rigidly in position. Asidewise-extending handle, 1), of lever D serves to carry the draw-headinto higher or lower position on releasing the pawl.

The draw-head and coupling-link may thus be set to the exact height ofthe draw-head and link of the car to be coupled with, and
